Hats off to you, norton. What you are attempting to do is a worthy yet difficult task as the variations on this kind of relationship are varied in the extreme (pun intended).

I am guessing that your system will classify bdsm on different, levels such as intensity, commitment, formality, range of activity, level of consent, sexual orientation and taste in fetishes. Already the permutations look daunting.

Regardless of how successful you are -and I do hope that everyone in the forum will help you come up with a somewhat scientific picture of the scene- there will always be people who will not fit into any categories.

If it helps I would describe my relationship with F. (my boyfriend) as monogamous, heterosexual, committed to bdsm but not 24/7, with play based primarly on sexual activity, intense but not extreme, sadomasochistic but not cruel or abusive, casual in level of formality and non-fetish specific. Kind of complicated as you can see.

If I had to describe myself words like masochist, sub, pain-slut, cum-slut, tease, bondage hog and part-time switch would come to mind. In fact this is a very good discussion I should have with F. sometime.

In the meantime, good luck!
